import android.support.v7.widget.Toolbar;
import android.view.View;

import android.widget.ListView;
import android.widget.Toast;
public class About extends AppCompatActivity{
ListView list;
String[] text = {
"Version"
} ;
Integer[] imageId = {
R.drawable.ic_info_black_24dp
};
private Toolbar toolbar;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.about);
// Set a Toolbar to replace the ActionBar. (doesn't work)
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
CustomList adapter = new
CustomList(About.this, text, imageId);
list=(ListView)findViewById(R.id.list);
list.setAdapter(adapter);
list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(About.this, "You Clicked at " + text[+position], Toast.LENGTH_SHORT).show();
}
});
}
}
about.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent">

<ListView

android:background="#drawable/about_background">
</ListView>
</RelativeLayout>

I think your ListView and Toolbar layout overlapping each other, that's why you are not able to see that. If you want to show ListView below the Toolbar then you have to set android:layout_below="#+id/toolbar" property in ListView like that
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<include
layout="#layout/toolbar"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/list"
android:layout_below="#+id/toolbar
android:background="#drawable/about_background">
</ListView>

How to access a Button inside a Toolbar in Android

I'm pretty new to coding so I might not express myself correctly, please bear with me.
I have a fragment inflated inside a layout that includes a toolbar. When I open the fragment, I want to add a button (not a menu, just a button to navigate to another fragment).
My issue is I don't know how to instantiate the button from my Fragment class to add an icon and an onClickListener.
Here's my xml files:
The layout that contains my fragment:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="be.ac.ulg.mobulis.Activities.MainActivity"
android:orientation="vertical">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/blue"
app:popupTheme="#style/AppTheme.PopupOverlay" >
<Button
android:id="#+id/toolbar_button"
android:layout_width="#dimen/margin"
android:layout_height="#dimen/margin"
android:layout_gravity="right"
android:layout_marginRight="#dimen/innerLargeMargin"
/>
</android.support.v7.widget.Toolbar>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_main" />
</LinearLayout>
The layout in which the fragment is inflated:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:design="http://schemas.android.com/apk/res-auto"
android:id="#+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="be.ac.ulg.mobulis.Activities.MainActivity"
tools:showIn="#layout/app_bar_main"
android:background="#color/orange">
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#f1f1f1">
</FrameLayout>
<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="start"
design:menu="#menu/bottom_nav_items"
android:background="#color/orange"
android:backgroundTint="#color/white"
design:itemIconTint="#color/white"
design:itemTextColor="#color/white"
design:itemBackground="#drawable/bottom_bar_tint_selector"
/>
</LinearLayout>
So what I want to do is something like
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
toolBarButton = (???).findViewById(R.id.toolbar_button)
}
activity_main.xml to add Button inside android.support.v7.widget.Toolbar
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"

android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="56dp"
android:background="#FFA000">
<Button
android:id="#+id/toolbarbtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"
android:layout_gravity="right"/>
</android.support.v7.widget.Toolbar>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!" />
</LinearLayout>

import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
Button toolBarBtn;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar)findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setTitle("Toolbar with button example");
toolbar.setSubtitle("Toolbar subtitle");
toolbar.setLogo(android.R.drawable.ic_menu_info_details);
toolBarBtn = (Button)findViewById(R.id.toolbarbtn);
toolBarBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(getBaseContext(),
"Button in ToolBar clicked",
Toast.LENGTH_LONG).show();
}
});
}
}
Set This onClick Listener in your parent activity of Fragment.
try this to access your button of toolbar from activity
private Toolbar toolbar;
toolbar = (Toolbar) findViewById(R.id.ar_toolbar);
Button toolbar_button = (Button) toolbar.findViewById(R.id.toolbar_button);
setSupportActionBar(toolbar);
toolbar_button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(ChatActivity.this, "Clicked", Toast.LENGTH_SHORT).show();
}
});
you have to write like below
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
toolBarButton = (Button) view.findViewById(R.id.toolbar_button);
where view is your view which you bind at your onCreateView in your Fragment.
What I do is to bind the View inside the activity and then create an interface who works with that View.
public class Activity implements ButtonListener{
//findViewbyId or Butterknife
void doSomething(){
toolBarButton.something()
}
Interface
}
public interface ButtonListener{
void doSomething();
}
Fragment
public class Fragment extends Fragment{
public ButtonListener mButton;
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
mButton = (ButtonListener)getActivity();
super.onCreate(savedInstanceState);
}
}
You can access button directly without toolbar using (Button) findViewById(R.id.toolbar_button).
Toolbar toolbar = (Toolbar) findViewById(R.id.ar_toolbar);
Button toolbar_button = (Button) findViewById(R.id.toolbar_button);
setSupportActionBar(toolbar);

Extra blank space on CoordinatorLayout with a ScrollView and ListView

I've created a Scrolling Activity using the Android Studio template, this created an activity.xml and also a content.xml which is included on the activity.xml who has a NestedScrollView into which I've added a ListView feed from an adapter, at first it only showed one item so I programmatically made the size of it to a fixed value so that it actually shows all the items, I was able to do that without a problem and the NestedScrollView wraps the ListView with no problem, however there is a blank space below the NestedScrollView that I realize was from the CoordinatorLayout by adding background colors to all elements, the CoordinatorLayout is the main tag in the activity.xml but I am not able to figure out how to remove this blank space since if I use wrap_content on the CoordinatorLayout it will actually trim my content to half the screen for some reason.
The other things that are worth to mention are that this blanks space is not showing if I rotate my phone horizontally, is only coming up on a vertical position. Also,
Does anyone know what might be causing this? Is not a big deal and I might even end up leaving it like this but it's just annoying to me I'm not able to figure out what's going on.
This is my activity.xml

Scrolling to view in CoordinatorLayout shows only partially the view

I have made an Android app containing a CoordinatorLayout with a AppBar and a NestedScrollView. In my NestedScrollView I have a list of items, and a button which scroll to an item in my NestedScrollView.
When clicking the button, the Android app scroll down to the item, but doesn't show the whole item, only partially: http://i.stack.imgur.com/8kuq0.png
I expected something like the following: http://i.stack.imgur.com/k0A5N.png
It seems like the amount the app needs to scroll is about the same size as the AppBar, in order to show the whole view. If I remove the scroll flag in my layout file below, I get the expected behavior.
What do I do wrong?
Update (12/01/2016): I've updated the pictures, so they are bigger. Furthermore as I wrote in Herry's response, I'm in doubt if View.requestRectangleOnScreen() is the right method to call, or if I should use a different layout then NestedScrollView.
My activity is coded as follows:
package com.example.sij.coordinatorlayoutbug;
import android.graphics.Rect;
import android.os.Bundle;
import android.os.Handler;
import android.os.Looper;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
TextView itemToNavigateTo;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
itemToNavigateTo = (TextView)findViewById(R.id.itemToNavigateTo);
Button navigatorButton = (Button)findViewById(R.id.navigator_button);
navigatorButton.setOnClickListener(navigateToItemListener());
}
View.OnClickListener navigateToItemListener() {
return new View.OnClickListener() {
#Override
public void onClick(final View v) {
new Handler(Looper.getMainLooper()).post(new Runnable() {
#Override
public void run() {
itemToNavigateTo.requestRectangleOnScreen(
new Rect(
0,
0,
itemToNavigateTo.getWidth(),
itemToNavigateTo.getHeight()));
}
});
}
};
}
}
And the layout file:

How to reference ID from other layout

Following this tutorial I moved my ActionBar (Toolbar) from my main layout to another layout and I include the toolbar to my main layout like this:

<include
layout="#layout/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"

And my toolbar layout is this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.Toolbar
android:id="#+id/my_toolbar"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:elevation="4dp"
android:theme="#style/CustomActionBarTheme"/>
</LinearLayout>
But I got the following error
Why I cant make reference of my toolbar if it has the same id? Can I include my toolbar and make reference so I can put elements below the toolbar?
Edit 1 - Activity Code
package com.marcelo.notemuevas;
import android.content.Intent;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ListView;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
ListView list;
String[] itemname ={
"Carpinteria"
};
String[] descripcion={
"Reparación"
};
Integer[] imgid={
R.mipmap.icono1
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar myToolbar = (Toolbar) findViewById(R.id.my_toolbar);
setSupportActionBar(myToolbar);
myToolbar.setLogo(R.mipmap.ic_launcher);
CustomListAdapter adapter = new CustomListAdapter(this, itemname, imgid, descripcion);
list = (ListView) findViewById(R.id.list);
list.setAdapter(adapter);
list.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
// TODO Auto-generated method stub
String Slecteditem = itemname[position];
Toast.makeText(getApplicationContext(), Slecteditem, Toast.LENGTH_SHORT).show();
Intent myIntent = new Intent(MainActivity.this, carpinteria.class);
myIntent.putExtra("key", 5); //Optional parameters
MainActivity.this.startActivity(myIntent);
}
});
}
public boolean onCreateOptionsMenu(Menu menu){
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu, menu);
return true;
}
}
Edit 2 - Solution
Now I make it work, I added a new Id to the include then I make reference to it like James Lockhart and Phan Văn Linh suggest (dont know why the first time didnt work) so my new question is, the IDs works like variables? only exist where it has been declared?
This is the working xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_height="fill_parent"
android:layout_width="fill_parent"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.marcelo.notemuevas.MainActivity">
<include
layout="#layout/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/toolbarLayout"
/>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#id/toolbarLayout">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Servicios"
android:id="#+id/serviciosTxt"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:background="#color/colorPrimaryDark"
android:textColor="#FFFFFF"
android:gravity="center"
android:paddingTop="18dp"
android:paddingBottom="18dp"
/>
<ListView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/serviciosTxt">
</ListView>
</RelativeLayout>
</RelativeLayout>
In your XML
<include
android:id=#"+id/toolBarLayout" // set the id for layout that contains toolbar
layout="#layout/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_below="#id/toolBarLayout"> // change my_toolbar to toolBarLayout
Then you access to your Toolbar by change
Toolbar myToolbar = (Toolbar) findViewById(R.id.my_toolbar);
to
LinerLayout myLinear = (LinerLayout) findViewById(R.id.toolBarLayout);
Toolbar myToolbar = (Toolbar) myLinear.findViewById(R.id.my_toolbar);
Please try this:
In your toolbar layout file, in the LinearLayout tag, set the 'android:id' attribute to a unique layout id name, for example: android:id="#+id/toolbarLayout"
Once you have completed (1), in your main layout refer to your toolbar layout file as follows: android:layout_below="#id/toolbarLayout"
Hope this helps.
